Specification of Letters Patent.

Patented Jan. 30, 1906.

Application flied may 2v. 1904. serai No. 210,035.

To (1n/l whom it may concern: r

Be it known that I, HENRY S. HALE, of the city and county ofPhiladelphia, State of Pennsylvania, have invented an Irn rovenwnt inSeat-Cushions, of which the ollowing is a specification.

My invention has reference to seat-cushions; and it consists of certainimprovements which are fully set forth in the following specificationand shown in the accom anying drawings, which `form a part thereo Theobj ect of my invention is to provide a convenient and inexpensive meansfor securing theupholstery upon sheet-metal boxl'rames of seat-cushions.

ln carrying out my invention I provide thc seat with'a box-frame havinglower llanges grooved on their under sides and combincd with clamping-strips fitting said grooves and adapted to clamp the edges of theupholstery tightly in the grooves, said clamping-strips eing drawntightly into place by a series of clamping-bolts.

My invention also consists in other details of construction which, toether with the features above specified, wil be better understood byreference to the drawings, inwhich-f Figure 1 is a perspective view of aseatcushion of the characterembodying my invention. Fig. 2 is across-section of a ortion of same on line 2 2 of Fig. 3, and Flg. 3 isan inverted plan view of one corner of the seat-cushion.

A is a box-frame made of sheet metal, having the upper flanges B andlower flanges C, the latter having the grooves J and the beaded edges C.This box-frame is preferably made of sheet metal formed into the i shapeshown,l

D represents sprin -plates secured at their ends to the sides o thebox-frame A at d and sustained upon coil-s rings E, which latter restupon cross s ats F, preferably formed of sheet metal. rIhe u holstery Gextends over the springlates E and boxframe and the edges are iroughtunder the lower flange C, ,as shown.

H represents clamping-strips and fit the grooves J ,being of lesscross-section than the cross-section of said grooves. Theseclamping-strips'are preferably made of channeliron, having the depressedor recessed portion h. The side edgesare also perferably p inclined, asshown, so as not to give too sharp a bend to the upholstery at g, whereitis lclamped in the grooves J b v the clampingstrips H. 'Ihe edges ofthe upholstery are thus protected and not liable to fray, and the stripsH act as strong portions to sustain all heavy wear and tear.

I re resents clamping-bolts and extend throug the clam ing-strips,upholstery, and

o ut departing from the spirit of the invention.

Having now described my invention, whatV I claim as new, and desire tosecure by Letters Patent, is-' l. In a seat-cushion, the combination ofa sheet-metal box-frame having a lower flange beaded at its inner edgeand having its under part provided with an upwardly-extending grooveparallel to the beaded edge forming a recess on the under part and anupward extending rib upon the upper part of sa1d flan @transversesupports for the springs exten ino over the beaded edge and resting uponthe upwardly-extending rib of the boxframe, springs sustained by `saidsupports,

upholstery extending' over the springs and box -frame and having its ede extending over the groove on the-under si e of the boxframe, aclamping-strip for clamping the upholstery into the groove, andclamping-bolts for drawing the strip into the grooves upon theupholstery. l

2. In a seat-cushionVthe combination of a box-frame having a lowerflange formed with.

an upwardly-extending groove spring de vices supported by thebox-frame,oupholstery extending over the spring devices and box-framevand having4 its edges extending over the under surface of the lowerflange of the box-frame, clamping-strips for clamping the ul holsteryinto the grooves, clampingbolts 'or drawing said strips into the groovesupon the upholstery, and sustaining crossslats for the spring structurehaving their AIO() ends extended over the lower flanges of the grooves,upholstery extending over the spring devices and box-frame and havingits edges extendin over the under surface o the lower flange o the boX-frame, clampingstrips formed of channelbars with the grooved portionextending downward awa from the upholstery for clamping the upho storyin the grooves, .and clamping-bolts for clamping the channel-bars uponthe upholstery extending through the lower flange of the box-frame andhaving their heads shielded by the grooves of the channel-bars.

4. In a seat-cushion, the combination of a box-frame having a lowerflange formed with an upwardly-extending roove on the bottom anupwardly-exten 'ng rib above the groove on the top and a beaded edge,spring devices supported by the box-frame upon the beaded edge and riband secured to the lower flange, upholstery eXtendin over the springdevices and box-frame and aving its edges extending over the undersurface of the lower flange of the box-frame, clamping.-

strips formed of channel -bars With the grooved portion extendingdownward away from the uphblstery for clamping the upholstery into thegrooves, and clamping-bolts for drawing said strips into the grooves ofthe liange of the box-frame and upon the upholstery said bolts havingtheir heads shielded in the grooves of the channel-shapedclamping-strips.

5. In a seat-cushion, the sheet-metal boxframe having upper flanges Band lower anges C the latter being provided with grooves J and beadededges C', in combinanation with clamping-strips H of considerably lesscross-section than the cross-section of the grooves, clamping-boltsextending through the clamping-strips and the lower flanges at positionscorresponding to the grooves, cross-slats F resting upon the beadededges of the lower flanges and clamped in position, springssupportedupon the crossslats, spring-plates sustained by the springs and securedat their ends to the box-frame, and `upholstery extending over thesprings and box-frame and having its edges clamped between the groovedportions of the lower flanges of the box-frame and the clampingp ates.

In testimony of which invention I hereunto set my hand.
